1 Claim.

This invention is a, combination window sash, stop and weather strip of special construction, and has to do with any removable window sash held in place and in any raised or lowered position by a beveled rail sliding in a beveled or angular groove in the window sash. The beveled' rail is described herein as a side guide rail for the sash. On one side of the window the guide rail is stationary, while on the other side it is so designed that it is movable inwardly and outwardly and held in contact with the sash by a series of coil spring devices which at all times keep the guide rail in perfect contact with a corresponding groove in the sash. By so doing it acts not only as a perfect weather strip holder, but also as a It will be noted in Fig. 2 that the vertical recess 1 in the side of the sash 2 is angular, and that the side of the guide rail 5 fits the angle, and comes into contact with the strip 8, which is the weather strip. It is usually triangular in section as shown. The sash 2 has the customary window glass 9.

Considering Fig- 3 there will be observed the 7 saw made slot ID. -This slot extends throughout certain and reliable holder when the sash is raised and lowered. In the accompanying drawing constituting a part of thi application for a patent,

Fig. 1 shows a front view of any standard window frame and sash, with this invention applied thereto.

Fig. 2 shows a sectional view taken on the line 2-2 of Fig. 1, and illustrates the stationary position of the side rail or guide rail.

Fig. 3 represents a cross-sectional view of the guide rail and illustrates a longitudinal saw cut slot which is the full length of the guide rails and takes care of any swelling that might occur due to atmospheric changes.

Fig. 4 is a sectional view taken on the line 4+4 of Fig. 1, and shows one manner of fastening the guide rail in an enlarged groove of the jamb or window frame with the guide rail arranged to be moved out of contact with the sash.

Fig. 5 is a sectional view taken on the line 55 of the Fig. 1 and shows the arrangement of the coil spring members with respect to the upper and lower window sash, and also illustrates in detail the preferred construction of the spring members and the adjusting devices therefor,

Fig. 6 is a side view of the adjusting bolt which is shown in Fig. 5 in the coil spring members.

Fig-7 is a side view of the coil spring by itself, showing also the nut attached to the spring.

Throughout the drawings the same number is used to refer to the same part.

The window has the frame I, upper sash 2, lower sash 3, and window sill 4. In Fig. 2 the guide rail 5 fits a corresponding groove in the frame I. The groove in the frame is usually rectangular as shown. The rail 5 has an opening through it, and a screw 6 is passed through the opening into the window frame whereby the guide the length of the guide rail and is introduced to take care of any swelling brought about by changes of moisture in the air which might interfere with raising and lowering the sash.

Considering Fig. 4.- it is shown that the frame I has an enlarged groove l3, but that the point H of screw [2 passes into frame I as before. The enlarged recess I3 is intended to admit the stop elements which are set out in Fig. 5.

Now considering Fig. 5 it will be seen that the guide rail I5 is placed against a coil spring l6,

through which passes axially a screw IT. This screw has at one end a slot I8 for the insertion of a screw driver. Engaging the coil spring at the end is a disk l9, near the head 20 of screw l1, andthe head 20 of the screw is arranged in contact with the plate or disk 22 at the bottom of the recess. The screw engages the nut 2| shown also in Fig. '7, and it will be seen that if the screw be turned with a screw driver the guide rail I5 will be pressed accordingly into the angular recess of the sash 2.

The leaf spring 23 shown in Fig. 8 is inserted at the junction of adjacent members of the window construction as a weather protection thus filling the space caused by spring adjustment between the sash and window frame or jamb.

In the operation, any pressure may be applied by means of the coil spring and screw devices to hold the sash in any desired raised or lowered position. The parts are intentionally simple and strong to prevent undue wear or injury.

Having now described my invention, I claim:

In a combination including window sash, rails and weather strips, a window sash having in the sides thereof angular grooves extending vertically, weather strips located in the pointed ends of the grooves, a window frame having vertical rectangular grooves in the sides, guide rails movably arranged in the grooves of the window frame, screws passing through said guide rails and adapted to secure said rails to the window frame at intervals, the said guide rails being located against the said weather strips in the said window sash, the said guide rails having at intervals screw passages through them, screw bolts engaging the rail on this side of the window is held stationary. said passages, the said screw bolts having end recesses whereby the bolts may be turned by a screw driver when the sashes have been removed, ends of the said bolts projecting into said grooves in the window frame and being arranged in contact with disks at the bottoms of the said grooves in the window frame, coil springs encircling the said bolts and arranged with ends against the guide rails at one end of each spring, each of the said bolts having a nut thereon and the other ends of the springs being in connection with said nuts whereby upon the adjustment of said nuts the tension of said coil springs may be regulated with corresponding pressure on the said guide rails and upon the said weather strips.
